CI Updates

[bennibbelink]

This fixes the CI permissions problems we're seeing (along with cymetric #195 and cycamore #583). Sorry that this hasn't gone as smoothly as possible, hopefully this is the last major refactor.

Changes are as follows:

• build_test.yml does not push any images to the cyclus GHCR. Instead it uses a local docker registry on the GitHub runner. This way we don't experience permissions errors with PRs from forks. This adds a tiny bit of complexity that I wanted to avoid, but honestly I think the workflow might be more intuitive now than in previous iterations. I tried implementing this without a local registry service but docker automatically tries to pull metadata so I was seeing lots of permission errors.
  • we still use build-contexts to "redefine" the cyclus image being used in downstream testing but now it references the image in our local registry
• publish_latest.yml is the only workflow that updates the layer cache. This way all workflows essentially pull the layers that build the dependency image in cyclus:latest. Most workflows pull from this cache
• code_coverage.yml has its own cache since its dependencies are slightly different, but I've included the ignore-error option so that cache-to won't stop a workflow from passing in a PR
• all workflows that publish images (publish_latest.yml and publish_release.yml) need to be updated from a branch on the upstream repository. This is similar to our previous strategy
• in the cycamore and cymetric PRs I changed the cyclus_tag/cycamore_tag in the Dockerfile to latest. This is to eliminate some verbosity in the workflow files and ensure users are using the latest versions when building from the Dockerfile

Once again I've reference branches in cycamore and cymetric corresponding to their respective PRs with these changes

Something this PR also does is add a trigger for code_coverage.yml on push to main. This will update the coverage reference in coveralls on a push to main. This did not exist before which I think is why we still see a coverage drop from 49%, we never ran the coverage workflow after merge to update the coverage of main

Hopefully we are done for now?
